Re: prevent dhclient from exting
Well, I am at a loss then. This is my /etc/network/interfaces:
sphere@sluis:~$ more /etc/network/interfaces
# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).
# The loopback network interface
auto lo
iface lo inet loopback
# The primary network interface
auto eth1
iface eth1 inet dhcp
auto eth0
iface eth0 inet static
address 192.168.1.1
netmask 255.255.255.0
network 192.168.1.0
broadcast 192.168.1.255
Seems pretty standard. It's really beyond me why your dhclient won't
exit. It is written in the manual that the retry statement governs a
standard interval of 5 minutens even if there are no DHCP offerings. I
can't find any reason in syslog why it would exit. See below for a
syslog snippet. I suppose my dhclient is run from ifup as well? This is
what I have installed dhcp-wise:
sphere@sluis:~$ dpkg -l | grep dhcp
rc dhcp 2.0pl5-19.1 DHCP server for automatic IP address
assignm
ii dhcp-client 2.0pl5-19.1 DHCP Client
ii dhcp3-common 3.0.1-2 Common files used by all the dhcp3*
packages
ii dhcp3-server 3.0.1-2 DHCP server for automatic IP address
assignm

Hi,
Hi,
I'm looking for a way to keep my box connected. Sometimes the
connections drops for various reasons:
- cable removed from modem/nic
- power outage
- booted without cable
The problem is, that dhclient just gives up:

From this point on, I need physical access to the machine to make it
connect again. I tried installing ifplugd and configured it for eth1,
but removing/replugging the cable does not have the desired effect.
According to syslog nothing happens and dmesg looks uneventful as well.
Anyhow, if there were a way to have dhclient keep running, I would not
have this problem, and my box could just regain connectivity itself.
Can anyone point me in the right direction, so far I have tried man
dhclient.conf and installed ifplugd for eth1, but no cigar.

Arjen

I run my dhclient (I'm using dhcp3) automatically from ifup and it
doesn't exit eventhough the dhcp server is down and there is no
DHCPOFFERS. It just continues trying after the default time (5 minutes).
If you run dhclient manually, you could try -w option. See man dhclient
for details.
